Your Low-Cal Lunch

Salad for lunch sounds like a great idea—as long as it's not just a helping of iceberg lettuce, some shaved carrots and ranch dressing. Elisabetta Politi, RD, MPH, Nutrition Director at the Duke Diet and Fitness Center in Durham, North Carolina, says eating a bowl full of veggies that's low on protein and carbs probably isn't giving you enough calories to power you through the rest of your day. "If you're eating a 200-calorie pile of broccoli and lettuce, it's no wonder you feel hungry and tired at 4 p.m.," Politi says. Instead, bulk up your salad with chicken, chickpeas, quinoa or edamame, for slow-burning energy. And, as mentioned earlier, beware of sugary salad dressings, such as honey mustard and raspberry vinaigrette. Olive oil and vinegar are a better choice.
